A Niche Theory of Interest Representation
The Journal of Politics, 1996The theory of organizational niches may provide important bridging concepts upon which an integrated theory of interest groups might be developed. After discussing Hutchinson's (1957) n-dimensional niche concept, we develop several hypotheses about the reliance of interest organizations on multiple resource dimensions. These are tested with survey data

Niche theory and community organization
Canadian Journal of Botany, 1988The ecological niche concept was developed by animal ecologists, and the concept has only recently been applied to plant population studies to any great degree. Many different aspects of the niche concept have been explored to determine the manner in which plant communities are organized.

Niche Construction Theory and Archaeology
Journal of Archaeological Method and Theory, 2010Niche construction theory (NCT) is a relatively new development within evolutionary biology, but one that has important implications for many adjacent fields of research, including the human sciences. Here, we present a broad overview of NCT and discuss its application to archaeology.

Niche Construction Theory and Ethnobiology
2015The focus of ethnobiological research is to understand the interactions between people and biota. Here we suggest that niche construction theory can provide an important “theoretical framework” for understanding these interactions from different perspectives.

Ecological Theory and the Superfluous Niche
Philosophical Topics, 2019Perhaps no concept has been thought more important to ecological theorizing than the niche. Without it, technically sophisticated and well-regarded accounts of character displacement, ecological equivalence, limiting similarity, and others would seemingly never have been developed.

Bryophytes and ecological niche theory
Botanical Journal of the Linnean Society, 1990Classical niche theory, particularly in terms of competitive exclusion, does not appear to apply as well to bryophytes as to other organisms. Bryophyte communities, as well as those of other plants and of animals, can be thought of in terms of individual species each utilizing particular portions of various resource or habitat continua.

Species coexistence and niche theory
2019Abstract Ecologists have long puzzled over the question of how multiple species may coexist in a community in the face of strong interspecific competition. This chapter explores the answers that modern coexistence theory provides to this question.

Spatial niches and coexistence: testing theory with tarweeds
Ecology, 2010Competitive coexistence in a spatially heterogeneous environment is traditionally attributed to niche differences, but several recent theories have proposed important additional roles for propagule limitation and chance (e.g., neutral theory, stochastic niche theory, spatial storage effect).

A niche for theory and another for practice
Trends in Ecology & Evolution, 2013The relation between niche and distribution is one of the most fraught in ecology. What is a niche? What has a niche? Do niches evolve? What are the mechanisms that translate niche into distribution?

Niche width theory reappraised
The Journal of Mathematical Sociology, 1997Niche width theory is a part of organizational ecology, which predicts for given environmental conditions whether specialist or generalist organizations will do better. These predictions are based on a mathematical model, but the model itself does not match the verbal argument, which in turn is ambiguous.
